I talked to Gary Meisenberg last night he was project manager of the Blackhawk drive

I was looking fo insite on the x-dim for my 20 he said from his original testing that on my straight botton 20 that I should put the bottom of the bullet at or one inch above the keel.

Inrteresting conversation he at on time had one that was cut in half and he could space down to arrive at the best running x-dim

Mine transom is already cut hope I dont have to refil and cut again

Klaw

are you doing an ITS or any set back?if you do keep in mind you need to go up an inch for every foot of setback. with it at one inch, that would put you at about 17.5 correct?

Rob I have drawn the transom with a ITS and blackhawk to get the dimension i will check tonight and send you PDF of where it will be

Geez, you guys are spending alot of time engineering....Gonna be pretty hard to pass that red and white one that got built in 2 months........

Especially with you driving!

Sell me your Blackhawk before you hurt yourself, and Wes breaks his foot off in your bruised ass.
